Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Ho wold is the child and what it is the pattern of contact which has been agreed
Is that the current pattern of contact?
How long has it been like that
Is it working for the child - and will it work once the child is at school?
In fact neither parent has the power to dictate how the child will share his or her time between them
There is no longer and concept of Custody and Access - or even Residence and Contact - there are Child Arrangement Orders setting out how care is shared between the parents.
If your ex seeks to change the current agreement and mediation is not successful and a Court application has to be made then it is likely that the current arrangements will be confirmed if they have indeed been working for the child
I hope that this is of assistance - please ask if you need further details
